The best method for opening files, as discussed in the WWDC sessions, involves using the new Preview Application API in Quick Look for visionOS. This API allows you to open files seamlessly within your app, providing a full spatial presentation. Here are the steps to do this:
- Using the Preview Application API:
- Create a custom view to represent the file.
- Add an on-tap gesture to this view.
- Call
previewApplication.openwith the URL of the selected file.
This method supports both individual files and collections of files, allowing for a more integrated and interactive user experience. You can also customize the default editing options and manage the lifecycle of the previewed files.
For more details, you can refer to the session What’s new in Quick Look for visionOS.
Additionally, for document-based apps or apps that manage files, the File Entity API in App Intents can be useful. This API allows secure access to files and can handle file operations like rotating an image in place.
